In August, a group of young people from Montana achieved an unprecedented victory in a climate change trial. As I wrote for these mark the beginning of a new era in environmental litigation. Represented by the nonprofit law firm “Our Children’s Trust,” these youth set a precedent that is now spreading across the United States and beyond.

Expanding the Movement

Virginia and Utah have similar cases coming up in appellate and supreme courts later this year. In “Layla v.

Climate litigation is not limited to the United States. Cases in Oregon and Hawaii, as well as in the European Union, are gaining momentum. In the European Court of Human Rights, the “Duarte Agostinho and Others v.

Recent Developments

One significant development is the ongoing hearing of the “Duarte Agostinho and Others v. Portugal and 32 Other States” case in the European Court of Human Rights. The case can now be watched online, allowing people worldwide to follow its progress.

Furthermore, the right to a healthy environment has become a central topic at…
